[minimal mDNS] Fix sending mDNS goodbye packets (#23661)

* [minimal mDNS] Fix sending mDNS goodbye packets

mDNS clients such as avahi would keep stale commissionable
node services in their caches because minimal mDNS did not
send "Goodbye" packets properly on service removal. That is,
it attempted to send records with TTL=0 in Advertise()
methods, called after RemoveServices() which clears all
allocated responders.

It could be reproduce by opening and closing the
commissioning window on the device because each open
operation regenerates commissionable node service instance
name.
